By the way, in theory a better way to make /sage "changeable" without using *any* extra diskspace is to create a new vdi disk, format it, then use something called "unionfs" to combine the /sage mount with that new formatted partition. This will make it so /sage still only takes 380MB, but the changes get stored uncompressed and take precedence over the read-only content of /sage. I haven't actually done this yet -- just read about it. But it is one of the key basic ideas on which the whole design of live cd's, puppy linux, etc., is based William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
